The melting point or conversely, freezing point can be defined as the temperature at which the solid and liquid phases are in equilibrium at a given pressure and basically, at which vapor pressures in both phases are equal. The two solvents used in this experiment were Hexane and Ethyl Acetate. This curve, whether the liquid in the middle is higher or lower than the outside, is called the meniscus. This is the reason why in terms of producing pharmaceutical drugs, pharmacists purify them to remove any trace of undesirable compounds. The following is the mechanism of the reaction: Figure 1. Synthesis Salicylic acid, a white crystalline powder, was weighed to approximately 2 grams, which was recorded in the logbook to be able to solve the percent yield, with an analytical balance and was placed in a ml Erlenmeyer flask.

Glucose-aspirin: Synthesis and in vitro anti-cancer activity studies. The melting point or conversely, freezing point can be defined as the temperature at which the solid and liquid phases are in equilibrium at a given pressure and basically, at which vapor pressures in both phases are equal. By inhibiting irreversibly the cyclo-oxygenase enzyme 1 and 2 isoenzyme , it prevents inflammation and platelet aggregation. This process is necessary because Aspirin is crystalline at room temperature, but when it is synthesized, it is in solution at a higher temperature. Introduction Organic compounds are a certain type of compounds that contain carbon.

This is partially because of the fact that Salicylic acid is a diprotic acid; this means that when Salicylic acid dissolves in water, it releases two Hydronium ions and makes the solution more acidic than if the same number of a monoprotic acid molecules were added. Then, after resetting the balance, take the large arbitrary amount of substance and transfer some of the substance to the desired beaker or other receptacle. The following is the mechanism of the reaction: Figure 1. To use this apparatus, one must use a small glass capillary tube to scoop up a small amount of the substance and then place this capillary tube inside the apparatus. By using molar masses and these whole number molar ratios, it is also possible to calculate the theoretical yield of the reaction. Crystallization is the deposition of crystals from a solution by which during that process, a molecule will tend to attach to a growing crystal composed of the same type of molecules because of a better fit in a crystal lattice compared to other molecules; these reactions could yield products that contain the presence of impurities.

It was purified then through the process of Recrystallization using solvents that will then yield a product to be tested for its purity and effectiveness using Physical and Chemical properties. Vacuum filtration can be used to help dry out a sample as well. Another laboratory technique used in this experiment is recrystallization. In , Felix Hoffmann discovered that there was indeed a way to make this drug less irritating to the throat and stomach: by reacting Salicylic acid with Acetic Anhydride, it would be possible to acetylate the Salicylic acid to remove one of these proton-donating groups and thus make it less irritating to the body. In the process of purification using purification, the melting range should decrease while on the other hand, the melting point should increase as the impurities are excluded during the successive purification until no further change is observed and thus the compound should melt sharply, before the compound is declared pure Pasto, In this experiment, the catalyst of Phosphoric Acid is used to catalyze the formation of Aspirin, which can be seen in the mechanism of the reaction in Figure 2.

Of course, all chemical compounds contain functional groups which are characteristic group of atoms or bonds that possess a predictable chemical behavior Klein, Jacob, J. In this case, Salicylic acid with Phenol group worked as the alcohol and Acetic anhydride with Carboxylic acid group worked as the acid with concentrated Sulfuric acid as the catalyst and in the end changed alcohol to an ester. Once all of the liquid is gone from the crucible, the solid should be rinsed with a solvent that will not dissolve the solid in order to wash out and trapped impurities. A Melt-Temp apparatus is used in this experiment as well in order to find the melting point of the synthesized substance.

Migal

It was in the middle of the 19th century when vacuum filtration was founded and is used in the laboratory by which Jules Piccard is the first culprit to advice this method based from industrial filtration. Data Salicylic Acid S.

Tugore

Just as how photosynthesis performed by plants and algae, generally autotrophs, would produce Oxygen after producing their main food source, starch with different ingredients and stages, the synthesis of aspirin would also yield by products that are considered to be impurities. Crystallization is the deposition of crystals from a solution by which during that process, a molecule will tend to attach to a growing crystal composed of the same type of molecules because of a better fit in a crystal lattice compared to other molecules; these reactions could yield products that contain the presence of impurities.
